FOMENTATIONS. 



To ensure the real benefit of fomentations with water 

 as a remedy for disease, the following directions should 

 be observed : — 



The temperature (about 11 8° F., and not higher than 

 120 F.) should be maintained throughout the applica- 

 tion, a plentiful and constant supply of water being pro- 

 vided. 



The affected parts should be covered from the first 

 with flannel, blanket, or the ordinary rug, folded one to 

 three times, to maintain the heat as much as possible. 



Application of the water should be prolonged ; in 

 severe cases, as much as four to six hours being required 

 to ensure benefit. 



At the close, fresh, dry, and warm coverings should be 

 in readiness to avoid reaction by sudden cooling. In 

 winter time this is doubly important. 



The operation is performed as follows : — The animal 

 being suitably placed, a large pail or open tub is brought 

 as near as possible and filled with hot water, the tempe- 

 rature being tested by a thermometer immersed into it, 

 and regulated by needful additions. The coverings are 

 then saturated, partially wrung out, and placed over the 

 affected parts, spreading as widely as needful, when the 

 process commences by carrying successive quantities 

 of water to the highest part, and pouring it over the 

 coverings, keeping up a continuous stream. In this way 

 it is only possible to maintain the desired temperature.
